In 2004, she ran as a Democrat for the Maine House of Representatives in Appleton. She won the general election with over 60% of the vote. After a year and a half as a Democratic member of the legislature, she authored the book Setting the Maine Course: We Can Get There from Here, in which she advocated a variety of new policies, including eliminating both the corporate income tax and economic development tax breaks, dedicating the sales tax to funding public education, having the state pay for Teacher pay, increasing environmental regulation, decreasing all other regulation, establishing a "rainy day fund" to cover budget deficits, and fighting urban sprawl. She says that she wants Maine to be known as "the Free Enterprise State."
